soil egg nutrient value is higher?
Although the nutrient value of soil eggs and general eggs has its own emphasis, it could have been ignored. Previously, dozens of batches of eggs in different regions, different types, and different breeding methods were inspected, and the results showed that the eggs produced by traditional rural free-range breeding methods and the eggs produced by centralized breeding contained protein, The contents of amino acids, vitamins, calcium, phosphorus, iron and other nutrients are basically the same.
It can be seen that native eggs are not synonymous with "high nutritional value". They are different from ordinary eggs and more reflected in the taste. The content of unsaturated fatty acids in native eggs is high, which is very suitable for making boiled eggs and fried eggs. Simple cooking methods can give full play to its excellent taste. If it is not different, the research data and food measurement data in animal husbandry show that compared with foreign eggs, the share of omega fatty acid and lecithin is slightly higher, which does have some advantages in promoting cholesterol metabolism and maintaining cardiovascular system.
See 3 big mistakes for native eggs
Myth one: farm eggs more nutrients. Real farm eggs (native eggs) may be better to eat. However, the inspection showed that the nutrient content of farmhouse eggs was not higher than that of ordinary eggs. In addition, the environmental hygiene of the laying of native chickens is not well controlled, and eggs are more likely to be contaminated by stool.
Myth 2: Red shell eggs are more nutritious than white shell eggs. In the past, people always thought that red shell eggs were more nutritious and the price of red shell eggs on the market was more expensive. The inspection showed that the color of the eggshell was related to the type of chicken and had nothing to do with nutrients.
Misunderstanding 3: "newborn eggs" and "functional eggs" are more nutritious. Generally speaking, eggs laid by chickens within 130 to 160 days of growth are called primary eggs. There is no evidence that the nutrient content of primary eggs is more than that of ordinary eggs. In fact, the first-born eggs are small, about 40 grams each. They are not allowed to be sold abroad because the weight is not standardized. The function of eggs refers to the feed technology to make eggs rich in zinc, iodine, selenium, calcium and other nutrients. This sounds excellent, but in fact, because there is no standard and poor inspection, many commodities are suspected of over-promotion.
How to choose eggs?
Look at the egg white. The egg white contrast of the native egg is sticky, and the color is a little yellow. It feels crystal clear when looking at it, while the foreign egg is not rich in nutrients, the egg white contrast is thin, and the color is white.
Look at the yolk. Open the eggshell, can see the proportion of egg yolk, egg yolk can be a lot of oh. Then the yolk can be quietly picked up with a toothpick, but it is difficult to do so with foreign eggs.
Scrambled eggs. Break the eggs, stir the egg yolk and egg white evenly, and then stir-fry. If the eggs are found to be scattered, it is foreign eggs. If the eggs are connected together, it is local eggs.
Smell the smell. Cook the eggs, then peel them off and smell them. If they are compared with the fragrance and taste good, it is clear that they are native eggs, but if they smell a fishy smell and taste bad, it is not native eggs.
